06 gt ,saleen supercharger,460 at the rear wheels.will the transmission shift as hard and firm as the old c4 or c6 or even my lightning?mine is suppose to be set as firm as it can be and is alot better than stock but 2-3 and 3-4 just dont have that seat of the pants snap shift to it.kinda feels like it wants to shift harder but something pulls back on it.hard to explain but it just doesnt shift as hard as the older trans.is this normal or should i have some one else try to re do it?
